Description

Technical Field

[0001] This utility model belongs to the field of equipment circuit technology, and more specifically, it relates to a connection structure for equipment circuit connection lines. Background Technology

[0002] In simple electrical circuits, point-to-point wiring is sufficient for connecting components. However, in complex circuits with a mix of series and parallel connections, space is limited. If point-to-point wiring is still used, multiple solder points will appear at a single lead-out point. Especially in high-voltage circuits, short circuits and voltage withstand failures are highly likely to occur at these connection points.

[0003] Existing technology includes a specification titled "Connector Cable End Structure" with publication number "213692490U," which relates to the field of connector cables, particularly to an end structure for connector cables. This structure includes a connector for connecting to a connector cable, the connector cable having a receiving groove for inserting and engaging with the connector cable, and a positioning block connected to the connector cable, the positioning block being positioned on multiple connector cables. This application aims to reduce the possibility of relative displacement between the connector cable and the connector cable. This existing technology does not address the technical problems and solutions of this application. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a simple structure for connecting equipment circuit wires that can greatly reduce the number of connection solder joints and ensure that the wiring position maintains good electrical performance under high voltage environment, in order to address the shortcomings of the existing technology.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0016] The working principle and beneficial effects of this utility model are as follows:

[0017] The device circuit connection structure described in this utility model requires the connection of multiple wires. A connecting base, which is a hollow cavity, is provided. Multiple grooves are provided on the side of the connecting base for the wires to pass through. The wires extend from the outside of the connecting base into the hollow cavity, meaning the connection ends of the multiple wires are located inside the hollow cavity.

[0025] The following description, with reference to the accompanying drawings, provides a more detailed explanation of the specific embodiments of this utility model, including the shape and structure of each component, the relative positions and connections between the parts, the functions and working principles of each part:

[0026] As attached Figure 1 -Appendix Figure 5 As shown, this utility model is a device circuit connection structure, including multiple connecting wires 1 and a connecting base 2. The connecting base 2 is a hollow cavity 4, and multiple grooves 5 are provided on the side of the connecting base 2. Each connecting wire 1 passes through a corresponding groove 5 and extends to the position of the hollow cavity 4. The connecting ends 6 of the multiple connecting wires 1 are located inside the hollow cavity 4 and are soldered together. The connecting ends 6 of the multiple connecting wires 1 are soldered together. The above structure addresses the shortcomings of the prior art and proposes an improved technical solution. In this structural design, multiple connecting wires 1 need to be connected. Therefore, a connecting base 2 is provided, which is a hollow cavity 4. Multiple grooves 5 are provided on the side of the connecting base 2 for the connecting wires 1 to pass through. The connecting wires extend from the outside of the connecting base 2 to the hollow cavity 4, meaning that the connecting ends 6 of the multiple connecting wires 1 are located inside the hollow cavity 4. The connecting ends 6 of the multiple connecting wires 1 are welded together, so that the connecting ends 6 of the multiple connecting wires 1 inside the hollow cavity 4 contact each other and are then welded together. Soldering can be used. This centralized connection of the connecting ends 6 of multiple connecting wires ensures that the connection reliability meets requirements and significantly reduces the number of solder joints during wiring, avoiding short circuits or voltage withstand failures caused by space constraints. The device circuit connection structure described in this utility model is simple in structure, greatly reduces the number of solder joints on the connecting wires, and ensures that the wiring position maintains good electrical performance under high-voltage environments.

[0027] The connector 2 has a ring-shaped structure with multiple grooves 5 around its side edge. This structure, with its multiple grooves, allows different connecting wires to extend into the hollow cavity through different groove positions, facilitating end-to-end connection. Simultaneously, the different connecting wires can originate from different directions, isolating them from each other and preventing tangling that could affect wiring.

[0028] The hollow cavity 4 is equipped with a potting silicone block 7. In the above structure, after the connection ends of different connecting wires are welded, high-pressure silicone is poured into the hollow cavity to form the potting silicone block 7, which reliably fixes the different connection ends and meets the pressure impact resistance requirements under high pressure environment.

[0029] The device circuit connection structure also includes a nut 3. The other end of the connecting wire 1 includes a connecting component connector 8. The connecting component connector 8 is equipped with pins. With this structure, when the connecting wire 1 is connected to the device, reliable contact between the connecting wire and the device is achieved through the pins of the connecting component connector 8. After the connecting wire 1 is properly connected to the device, the nut 3 is tightened onto the threaded sleeve hole on the device to reliably fix the connecting wire 1. The end of the connecting wire 1 without pins is a connecting terminal 6, used for reliable soldering of connecting terminals of different connecting wires. The solder joints of different connecting terminals must be smooth, rounded, and without sharp corners.

[0030] A protruding limiting part 10 is provided at one end of the connecting wire 1 near the connecting end 6. In the above structure, the protruding limiting part is designed to lock into the inner surface of the hollow cavity of the connecting seat after the connecting wire is welded, thus ensuring the reliability of the connection and preventing it from falling off when subjected to external pulling force.

[0031] The component connection end 8 is provided with a nut limiting part 9. With this structure, after the nut is installed and wired, the nut is reliably engaged in the nut limiting part 9, achieving reliable positioning.

[0032] The connecting seat 2 is made of polyetherimide. The nut 3 is also made of polyetherimide. The above structure limits the materials of the connecting seat and the nut; the selection of the polyetherimide material ensures pressure resistance under high-pressure conditions.

[0033] The device circuit connection structure of this utility model includes a connector 2, which is a hollow cavity 4. Multiple grooves 5 are provided on the side of the connector 2 for the connecting wires 1 to pass through. The connecting wires extend from the outside of the connector 2 to the hollow cavity 4, meaning that the connecting ends 6 of the multiple connecting wires 1 are located inside the hollow cavity 4. These connecting ends 6 are welded together, so that the connecting ends 6 of the multiple connecting wires 1 inside the hollow cavity 4 come into contact with each other and are then welded together. Soldering can be used. This centralized connection of the connecting ends 6 of multiple connecting wires ensures reliable connection while significantly reducing the number of solder joints during wiring, avoiding short circuits or voltage withstand failures caused by space constraints.
